I have nothing up yet as I am waiting for my walls to be painted but at one point I had up a John Lennon "Imagine" poster, a Wizard of Oz movie poster, a Doctor Who poster and two mini Hetalia posters-nothing too extraordinary.

I had a sith poster a friend got for me, but after a few years now I'm taking it down, right now my Diploma is hanging up where it was, but I plan on printing out one of my photoshop images and hanging up there landscape. It's just 3 chao renders with a normal blue one sitting, and the evil and pure chao faded on both shoulders of the blue one.

One seriously big Kara no Kyoukai poster, an FMA: Brotherhood one at the same size. Two smaller KnK posters. Scott Pilgrim poster, got it with the collection box-thingy with all six books. One poster the size of a door, with Ezio from AC: Brotherhood. Two Skyrim posters and some maps from various games. My walls are almost filled with posters, so i can't buy much more of them now. Then i'll have to take some of them down, and switch them out with new ones :/

I took them all down when I grew the fuck up and moved out of Mom's house, now it's bladed weapons, most I have on display is cheap Ebay stuff (including a Cloud Buster Sword and an Ichigo wooden Sanpakto), but I have a couple of old bayonets and a civil war confederate sword that I keep packed away cause they're in kinda iffy shape that and I want to get some good boxes to display them in. I have a (replica) 1800's era dueling pistol set up on the wall. Oh, and I do have 1 poster, its an 18 year old Spiderman poster I found rolled up in a tube at a thrift store for like a buck, since I like "old" stuff I framed it and put it up.
